You should really consider a few mods before you throw in the towel. Frankly, as "tuneable" as these turbo I-4s are, I am surprised that we aren't seeing/hearing about more software updates. With a few tweaks to the code, an exhaust, and a cold air intake, I bet you can pull another 100 ponies out of a 328i for not too much $. I would check out what some of our Bimmerfest sponsors are offering or have under development.
